Precipitate Comparison Test; Borax and Sea Salt with Calcium Silicate

I perform a quick precipitate comparison between borax and sea salt with calcium silicate. The difference is startling to say the least.





I note that much of the precipitate has got to be the eroded material from one of the plates. This can only mean that there is a high concentration of Chromium in the sea salt sample and a simple 1/4 teaspoon of ferrous sulfate will not be enough to reduce the Cr(VI) to Cr(III).

Observational Electrolyte Test using Borax

I conducted an observational electrolyte test using borax and comment on the results.



My Observations

1. Foam begins to appear at around 5 minutes into the test

2. Once the foam thickens an occasional large bubble forms sometimes more of them but just a few at a time.

3. White particulate forms in minute quantities.

4. Particulate gradually changes to orange-brown

5. Particulate formation increases toward end of test. This leads me to believe the particulate formation is delayed compared to other electrolytes

6. White foam picks up some brown color before dissipating.

7. Once the foam dissipates, it leaves a scum behind.

8. For this test the brown particulate accumulation was light.

9. The plate has a gray buildup similar to what was observed with magnesium sulfate.
